I presume the libtiff.so must be present on the system, but not the TIFF
headers.
More likely the libtiff.a since compiling the conftest.c tests for it
(with -ltiff). In Linux Mint that would mean a broken libtiff-dev
package - at least that's how I can reproduce the case in it.
Interesting that a such situation should exist in a FreeBSD test
environment.
Likely development package of libtiff missing.
GDAL's configure apparently only check the presence of the .so but doens't
check that the header is available.
Yes.
Internal tiffio.h is included by internal libgeotiff if GDAL detects use of
internal libtiff (TIFF_SETTING=internal in GDALmake.opt)
But it wouldn't be correct for the internal libgeotiff to include the internal
tiffio.h and linking against external libgeotiff.
I guess in this case the best way is to explicitly set
--with-libtiff=internal.
So the immediate fix is make sure libtiff headers are present on the system
(or explicitly select internal libtiff in ./configure)
And an improvement in configure.ac would be also welcome to check that the
headers of external libtiff are available.
Maybe AC_CHECK_HEADER could be used in addition.
BTW, interestingly the "Check if user requests renaming internal
libgeotiff symbols" seems to appear twice in the configure.ac.
